There is some overlap, and it raises questions as to where to properly put posts. For example, should Oregon Pinot Noir go in Northwest Wines or Pinot Noir? I suppose it's not a big problem (I resolved the above dilemma for myself by putting all my Pinot notes in the Pinot thread, but putting all other Pac NW wine notes in the NW thread).

As one who has called for more categories in the past, e.g. South America; I'm a little concerned about too much revision. If we elimiated categories what happens to the threads on them? If we add more, things could get unwieldy.

Syrah fits nicely in the Rhone category, and Shiraz fits nicely either there or in Australia et al.
